Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, by the following examples, and tie
Close accompanying drawing, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to solve
Release this utility model, be not used to limit this utility model.
Shown in Figure 1, this utility model rotary compressor one embodiment, a kind of gas provided including this utility model
Cylinder, this cylinder includes cylinder body 110, and the sidewall of cylinder body 110 is provided with air inlet 120, and air inlet 120 includes outlet section 121 He
Article at least two, entrance 122, outlet section 121 and cylinder body 110 intracavity inter-connection, one end of entrance 122 is with cylinder body 110 outer wall even
Logical, the other end is connected with outlet section 121.Being provided with circular piston 130 in cylinder body 110, piston 130 is connected with bent axle 140,
Being provided with slide plate 150 on cylinder body 110, cylinder body 110 inner chamber is divided into suction muffler 111 and compression chamber 112 by slide plate 150 and piston 130,
The outlet section 121 of air inlet 120 is connected with suction muffler 111, and gas enters cylinder body 110 by least two entrances 122,
Outlet section 121 enters in suction muffler 111 after converging, and in the case of reduction cylinder body 110 height, at least two entrances 122 are also
Can ensure that the circulation area of air inlet.
As one preferred embodiment, the cross section of outlet section 121 is rectangle.The outlet of square-section reduces compression
Machine air-breathing trailing edge angle, reduces air-breathing backflow, is easy to again processing and manufacturing.
